Patent EP-0012438-A1 (EP)
Inventor: SIMPSON FRANK F
IPC: B25D11/12
Filed: 1979-12-13
Abstract: A percussive tool has a percussion mechanism driven by a linkage that combines the simplicity of a connecting rod drive with the compactness of more complex drives. A first member, which may be a crank (6), drives a second member, which may be a cylinder (20), mounted for sliding and pivotal movement in a guide (22). A piston (21) is mounted for reciprocating movement in the cylinder (20). Rotation of the crank (6) reciprocates the piston (21) causing blows to be imparted to a tool piece. The tool piece is rotated as well as being subjected to percussion.

Abstract: A dried, non-dairy food composition such as a powdered coffee whitener is provided which contains liquid fat (at room temperature) encapsulated or enrobed by a specialized, carbohydratecontaining matrix. In preferred forms, polyunsaturated liquid fat can be used for dietary purposes, and the matrix can be protein-free if desired. In preferred practice the matrix normally contains a carbohydrate such as corn syrup solids, an emulsifier system having at least two anionic emulsifiers, and other optional ingredients added for organoleptic or nutritional reasons. The composition is formulated by heating and mixing the fat with the matrix-forming ingredients, subdividing the fat into particles of no more than about three microns in diameter by homogenization, and spray drying the resultant blend to give the final dried composition.

Abstract: A wafer holder for liquid phase epitaxial (LPE) film growth is shown. The holder (10) hastwo legs (12,14) to which the top ring (16) is connected. The ring (16) has holding means (19) so that it can hold one wafer (18) or two wafers (18, 20) back-to-back. The leg (14) extends vertically below the ring (16) and a second ring (21) having holding means (25)for a pair of wafers (24, 26) back-to-back is attached to the leg (14). This holder structure prevents a film from the liquid melt from forming between the wafers (20, 24) when the holder is withdrawn from the liquid growth solution, thereby eliminating the formation of mesas which occur when such a film ruptures.

IPC: G01N23/04

Abstract: For the backprojection of the convoluted measurement signals in a cartesian coordinate system in a computer tomography device, it is necessary to recalculate the weighting factors for each position of the source (1) in orderto determine the contribution of a convoluted measurement signal to the attenuation value associated with a given element ( E ) of the output image matrix. This is a time consuming and hence expensive form of reconstruction, and can be avoided by storing all the weighting factors required; this, however, implies a very large memory, and is also expensive. 
     The invention relates to the use of a matrix of elements ( E ) organised in polar coordinates, which is stored in the memory, (17a) the origin central coordinate (40) of said matrix coinciding with the centre (9) of rotation of the X-ray source (1) about the object section (7). The weighting factors are also stored in a polar organized memory (17b). The angular component of the address of the weighting factors is incremented with a rotational increment in the corresponding position of the X-ray source (1 ), so that for each group of measurement values, the same weighting factors can be used. The invention enables all the weighting factors to be stored in a memory (17g) of limited capacity, the more so because all weighting factors are mirror-symmetrical with respect to a central axis connecting the X-ray source (1) to the centre (9) of rotation, so that the angular coordinates of the memory (17) need only extend from 0 to π instead of from 0 to 2 7T .

Abstract: A device (A) for supplying a succession of die cuttobacco blanks (W) with a given profileto a web (64,66) of a coiled type, storage bobbin (60,62). This device comprises a set of die cut stations (20,30) each including a cutting die blade (72) with an upstanding cutting edge (74) matching the profile of the proposed blank and vacuum means (86) surrounding the edge of the blade for capturing a tobacco sheet material on the stations in a position overlying the cutting edge. The stations are moved along an endless, preselected cutting path (P) which intersects a cutting means (100) at a first fixed position in the path of movement of the stations so that a tobacco leaf can be cut from a manually placed tobacco sheet captured on the movable station. After passing the cutting means, which includes two rolls (102,104) generally fixed in the direction of movement of the station, the station continues in the same endless path to a transfer position at which position the cut profile (W) is released from the cutting station and is transferred to an awaiting web of a coiled type storage bobbin.

Abstract: The system comprises bidirectional two-wire transmission lines (DL), branching nodes (AK), subscriber stations (TS) including a subscriber modul (TSM) and generators (SG) and (SR) for generating and reflecting periodic synchronization information. The system enhances the number of subscribers connectable to the network and improves the system reliability against cable flaws, component failure and tapping of the information. In the system the time-position addressed information only is sent on the direct path between the corresponding subscribers. Therefore one and the same channel can be used by a lot of simultaneous independent connections. For example connections between the subscribers (A) and (B) resp. as well as between (E) and (F) resp., are established via channel 1. For a connection of subscribers C and D another channel must be chosen, eg. channel 2. 
     The architecture of the system allows its realization as a line-, ring-, branched-, star- and mixed structure.

Abstract: An automobile air conditioning system is provided with a control system for controlling the flow rate of hot or cool air discharged into the passenger compartment. The air flow rate is controlled in relation to the sensed value of the ambient air temperature and the temperature of a heat source of the air conditioning system. If the sensed temperatures are lower than predetermined reference levels, the air flow rate is gradually increased at a moderate increasing rate. The air flow rate is more rapidly increased when the sensed heat source temperature is higher than the reference level.
